Answer:
b)It is a compound because it is made of a single kind of molecule.
Explanation:
A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).
<h3>Mitogen-activated protein kinase :</h3>
A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.
In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.
Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.
The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.

Carbon capture and sequestration
While it's not a power generation technology, carbon capture and sequestration—technologies that allow for the scrubbing of carbon from power plants for storage in underground reservoirs—may finally be coming of age after years of trial and error.
Technology pilot demonstrations at coal-based power plants in places like Australia and the U.S. have sparked new interest in the technology.
The hope is, it could become an enabler for other technologies, such as biomass or algae-based biofuels that produce carbon emissions. That's because organic fuels pull carbon from the atmosphere before converting it to fuel.
The age of the earth can however be derived from prior knowledge of the age of the Canyon Diablo meteorite.
<h3>What is Age?</h3>
This is defined as the length of time during which a being or thing has existed.
The fragment of the Canyon Diablo meteorite determined the elements that formed as radioactive uranium decayed over billions of years.
